The galaxy is moving at a staggering 4.5 million miles hour causing a lot of its gas to be stripped away. This process is known as ‘ram pressure stripping’. The gas that has been ejected can be seen to be forming new stars. It is a wonder that the galaxy is still held together. A nice demonstration of the power of gravity as it is this force that is keeping the main galaxy in one piece.
